Independent assortment of chromosomes is a result of _____.
Ann [662]

Answer:

the "second law of Mendel", or principle of independent distribution, states that during the formation of gametes, each pair of alleles segregates independently of the other pairs.

Explanation:

Mendel's second Law is also known as the Law of Segregation, also as the Law of Equitable Separation, and also as the Law of Disjunction of the Alleles. This Second Law of Mendel is fulfilled in the second filial generation, that is to say, from the parents to the first generation, the First Law of Mendel is fulfilled, and after the children of the first generation this Second Law of Mendel is fulfilled.

This 2nd Law of Mendel, speaks of the separation of the alleles in each of the crossing between the members of the first generation, who would now become parental of the second generation, for the formation of a new child gamete with certain characteristics.

Since each allele is separated to constitute features that do not belong to the first filial generation, but to that of the parents. That is to say that many of the most obvious features in the recessive allele would be present when a generation leaps. All this in relative proportion to the number of individuals in the second subsidiary generation.
